Assignments Homeworks: Problem sets will be assigned from the textbook and elsewhere. You are expected to work on the homework individually. Homeworks should be submitted in the class on the due time. 9. Computer Usage Students will need to use computers to solve homework problems, since open-ended and iterative problems may be assigned. You may use any software package you are most familiar with. SolidWorks, SolidEdge and MS Excel are possible ones. In due time, you may also be provided with some commercial or inhouse programs to help you with the design process. 10. Attendance Attendance will be checked at the beginning of each lecture. Late coming is not encouraged as this disturbs students and instructor. Excuses for absence should be approved by the Deanship of Student Affairs and submitted to the instructor within one week following the last day of absence. Any student who has more than 9 unexcused absences will get a grade of DN (Denial). Any student who has more than 15 unexcused + excused absences will get a grade of W (Withdrawn) for this course, provided that his unexcused absences are less than 9. 11. Exams The Major and Final Exams will be open book. You will be allowed to prepare one single sheet listing all important formulas that you need. Both sides of the sheet can be used. Major Exam 1: Date & Place: Sat March 24, 2007, at 8:00 pm. Major Exam 2: Date & Place: Sun April 29, 2007, at 8:00 pm. Final Exam: Date, Time and Location: As will be announced by the Registrar. 12. Grading Attendance+Homeworks 9% Quizzes 6% Major Exams Final Exam 13. 50% (2x25) 35% Student Learning Outcomes Course Objective 1 1. Students will demonstrate ability to use free-body diagrams, equilibrium equations, force, moment and torque diagrams, and calculate resulting stresses. 2. Students will demonstrate how to find relevant properties of materials from various sources. Course Objective 2 1. Students will demonstrate ability to compute principal stresses in different machine members subjected to combined loadings. Course Objective 3 1. Students will demonstrate ability to calculate principal stresses and extreme deflections for various cases of loading, and check criteria for failure due to yield or due to unacceptable deflections. 2.
